I had 3 interviews for a junior positions. HR talk, technical and team lead talk. The technical one is not hard if you practice with Codewars often, like 6-7 Kyu.

Part one

2 coding exercises

1. There is a string, write a function to count the occurrences of each letter.
2. Unit testing


function get


Part two
1)Regular function and arrow function (no this context and cannot be a constructor)
2)Null and undefined （typeof (null) => object)
3)async await what do I know
4)data types
5)immutable data types
6)var, let, const
Var function scope (for loop example)
Let and const both are block scope
7)deep copy and shallow copy (iterable and iteration to learn well; spread operator)
8)specificity in css
9)semantic tags
10)position positive and relative
11)Inheritance??
12)event bubbling
13）Angular and React which one I like



Extra talk：
1. There is something happening between the server and the client. As the time goes by, the users make requests to the server and every time, there was no response from the servers’ side. How would the developer solve this issue so that the users can see the response that the server is having some issue now to avoid that many unnecessary requests?
